Abstract

Cette invention a trait à une antenne à même d'accroître les capacités d'un système cellulaire de communications. Cette antenne, qui fonctionne en association avec un poste d'abonné mobile, comporte plusieurs éléments d'antenne, couplés, chacun, à un déphaseur programmable respectif. La phase de chaque élément d'antenne est programmée aux fins d'une réception optimale durant, par exemple, un fonctionnement en mode repos avec réception d'un signal pilote. Le réseau d'antennes crée un formeur de faisceaux pour des signaux que doit émettre le poste d'abonné mobile ainsi qu'un réseau directionnel de réception afin de détecter et de recevoir, du mieux qui soit, des signaux envoyés par la station de base. Le fait de procéder à une réception et à une émission directionnelles des signaux, réduit notablement l'évanouissement dû à la propagation par trajets multiples ainsi que l'interférence intercellulaire. Cette invention porte également sur diverses techniques permettant de déterminer la phase appropriée de chaque antenne.
